such as are used for main and'counter-shafting, etc., and which are mounted by. means of hangers, pedestals, brackets, etc.

The purpose of my invention is to provide take-ups for divided bearing members,fad justing lfrom the side and one of which lifts both bearing members..

A, vfurther purpose is to divide the bearing at the top and bottom, make the adjustmentof the two parts laterally, and combine vertical and lateral adjustment in'one member and lateral adjustment onlyv in the other member by which the bearing is formed. y

A further purpose is to mount one of two laterally movable bearing parts upon a sloping support or seat along which it is adjustable, and to mount the second member upon a horizontal guide carried bythe first. A further purpose is ltovform a hanger or pedestal. of flanged sheet metal to rwhich flanges of a sheet metal support or seat 'for the bearing membersare attached in caiited position and to adjust the bearing members by screws at the ends of the suppoit.

Further'purposes will appear in the speciflcation and in theclaims.

l have preferred to illustrate -my invention by but a few of the possible forms from among the many typesl and kinds of construct-ion to which it may be applied, selecting forms that are practical,eiiicient, reliable and inexpensive and which at the same time well illustrate the principles of my invention.

In its broadest `aspects one feature of my invention lis independent ofL .the 'character of support, whether :cast iron orV pressed metal and whetherihanger, bracket or pedestal,` etc. This broad feature runs through the several figures ofthe application, dependfing asit does, upon provision of'an outside sloping support for.l one of*4 twoy laterally movable bearing members anda support upon `the lirst for the: other bearing member, the second support being horizontal. g However, another phase. of my invention relating to the construction ,of5thej support for the bearing parts toprovide theiirsttoutside) support is dependent fupon pressed metal j' construction. p

Taking up the pressedlnietal construction first, because itis the most desirable construction from a manufacturers and users standpoint, I vshow a pair vof bracketsides 12, shown in useasparts of a hanger'and comprising each a web 13 and a surrounding flange let.HV 'lfheflanges'face oppositely and the sides/vary in, general contour` withv the size and strength. required. The .bracket edges vare recessed at' 15v torallow the passage of a transversely disposed shaft 16 and to accommodatethe endsf 17, 18 oflaterally movable bearing members 19and'20. Y

j .The division between these bearing members atf21 and 21, is transverse to the paths .of movementof thefme'mbers, here preferably within or near a vertical plane through the axis oftheshaft 16, .sothat the bearing members may be adjusted laterally to tighten upfthe bearing.. c

The. hanger sides are secured tothe beam 22 by means of bolts'23 passing. through slots. 24 in the flanges. v.These vslotspermit lateral adjustment of the-:hanger where desired to' assist in height,adjustirient.jV y

.Between the sidesv I placea connecting ioo base25 comprising. a support'for the bearing having the left end in Figure 1 higher than the right, the more convenient construction for this form. f Y

Upon the seat is placed a preferably cast metal bearingfmemberl 20 whichl has a tapered base 31 whose taper is intended'approximately to conform with the slope of the seat 26, so that the bearing member shall be adjustable from right to left in the illus tration to move the interior 32 of the bearing member toward the shaft and at the same time to lift the bearing member bodily along the taper of the seat.

AThe lifting effect may be increased by moving the hanger vto the right (for which the slots offer room) and then tightening` up the member 2O by the additional distance and `Vvertical adjustm'ent separately may be secured by this means.

The bearing member 2O projects at the left to vform a tapered extension whose upper surface provides a support in the form of a guide 33 for the second bearing member. I make the guide 33 horizontal.

Upon the guideBS is mounted lthe bearing member 19 whose inner face 34 cooperaltes with the face 82 of member 2O to substantially enclose and to support the bearing. A liner 35 is ,placed between the inner facesj32 and 34 of the bearing members and the shaft. VIt may be integral, cut at one point 26 only as in Figure 1 or maybe split in parts as in igures 7 and 8 with any departure from the normal slope of the adjoining edges as at 37 and 38 in Figures 7 and 8.Y

Ufheflange 29 is riveted to the ange 14 through openings 39 byrivets40 and both flanges 28 and 29 are apertured at 41 to re ceive adjustingscrews in the form' of studs 42, adjusted and held in place by nuts 43 located on opposite sides of the respective flanges 28 and 29.

Bolts 44, 44 pass through the bearing members and the seat in the positions to which they have been adjusted and, to a1- low adjustment and a vsecond fastening in the adjusted position, either the seat or the flanges 45, 46 may be slotted as at 48 and thev other one apertured. In each case on acn count of the taper I have shown a taper washer 49. .One bolt 44 and bolt 44 pass f and the bearing member 2O is placed in position upon the seat before the hanger is placed. 'The bearing member 19.1is then tion at thebotto'm -by the bolts through the seat and flanges. .p

In use the shaft sags relatively, causing a wear at the bottom of the bearing which has not hitherto properly been compensate ed for in bearings having approximately vertical division lines, but my sloping seat for the bearing members causes one bearing member to lift at the same timethat it" a'djusts` the wear from the side. Since the bearing member 19 can move upon the bearing member 2O without change of its height, the left hand bearing member can be adjusted freely totake up lateral wear and is itself adjusted vertically along with lateral and vertical adjustment of bearing member 20. Adjustment of the bearing member 2() toward the shaft causes both bearing members to be lifted also, and one member to be adjusted laterally. Member 19 must be additionally shifted to lthe right in the illustrations to make up for the move-ment of Amen'iber 2O to the left.

,'Ihe liner 34 being axially insertable and removableY gives opportunity to substitute other liners for those showing wear.

The linercan be maintained in any positions desired by use of a key 53 fitting into a recess in one of the bearing members.

Inv the form showin` in Figure 9 the seat- 26 is shown as integral with legs 54 and with lugs 55, 56 by which the studs 42are sup ported. The bearingfmembers 19', 20 are of the same general. character as those seen in Figures1-6 and bear the same relation to the seat and lugs. The same type of fastening devices at the tops of the bearing mem bers through flanges and 51 and bolts 44 through the lower flanges perform the same functions as in the structures of Figures 1-G.

In the form shown in Figure 10 the parts are in the same general form and the same general relation as in Figure 9 with the dif-- ference, however, that both bearing memg bers 192 and 2O2 are lifted to give additional roonr and are recessed about and transversely to the shaft at 57, 58 and 59 to allow an oiling chain 57 to serve for oiling purposes. The lower part of the chain rests'within oil in a pool 58.

In all of the forms one of the bearing members is mounted upon a sloping-seat and thev other is mounted upon the first.y By this means adjustment of the lirst member up the slope of the seat tightens it laterally and at the same time lifts both members to any extent, determined by the .amount of if such as come within the reasonable spirit and scope of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent isn l. In a shaft bearing, a support, a seat thereon at an angle to the horizontal, a bearing member adapted to fit about the shaft on one side `laterally with respect to the seat as a base, having a tapered bottom portion resting upon the seat at its lower surface and forming a guide at its upper surface whose length is generally transverse to the. shaft, a second bearing member adapted to fit about the opposite side of the shaft and resting upon the guide on the first bearing member and fastening devices for holding the bearing members together and retaining them in set position with respect to the seat.
